Two 2.0-cm-diameter disks spaced 2.0 mm apart form a parallel-plate capacitor. The electric field between the disks
Question:
Two 2.0-cm-diameter disks spaced 2.0 mm apart form a parallel-plate capacitor. The electric field between the disks is 5.0 × 105 V/m.
a. What is the voltage across the capacitor?
b. An electron is launched from the negative plate. It strikes the positive plate at a speed of 2.0 × 107 m/s. What was the electron’s speed as it left the negative plate?
